Setting up several disks to work as a single disk
You can set up two or more disks or volumes to work together as a single, large volume.
- In Disk Utility, select one of the disks you want in the set and click RAID.
- Type a name for the set and choose a format from the Volume Format pop-up menu. Usually you will choose the Mac OS Extended (Journaled) format.
- Choose Concatenated Disk Set from the RAID Type pop-up menu.
- Click Create.
- Drag the disks you want to use to the set.
You cannot remove individual disks from a concatenated disk set.
